POLlsHING-MACHINE.

SPECFIGATION forming part` Of Letters Patent NO. 708,858, dated September 9, 1902-.

` Application filed March l0, 1902-v Serial No. 971489- (NO modem T0 a/ZZ whom, it may concern:

Be it known that I, JOHN WILSON BROWN, J r., a citizen of the'United States, residing in Philadelphia, Pennsylvania, have invented certain Improvements in Polishing-Machines, of which the following is a specification..`

My invention relates to certain improvements in machines for polishing metal surfaces, and especially machines for polishing the surfaces of flat-irons.

The Object of my inventionis to construct a machine in which a number of sad-irons or other articles can be polished, the sad-irons being held in chucks on the rotating frame, so that the sad-irons are brought into contact one after another with the polishingwheel, the irons being rotated as they come in contact with the wheel, as fully described hereinafter.

In the accompanying drawings, Figure l is a side View of my improved polishing-machine. Fig. 2 is a plan view; and Fig. 3 is a lsection on the line 3 3, Fig. 2.

A is the base of the machine, on which is a sliding frame B, having bearings b b'for the driving-shaft C. On this shaft is a step-pulley c and a polishing-wheel D. This wheel is made up of. a number of layers of fabric suitably clamped in the ordinaryA manner.

. d is a screw having oneendmounted in a bearing a, on the frame A, and this, screw passes through a nut b on the sliding frame B. On the screw is a hand-wheel d', by .which it is turned, so that the polishing-wheel D can be moved toward and from the work.

A' A2 are standards carrying the bearings a. for the shaft E, on which the carryingframe F is mounted. The carrying-frame F is driven through the following means:`

e is a belt leading from any suitable powershaft. This belt passes around guide-wheels e' on a bracket a2, projecting fromthe frame A, and the belt then passes around a wheel e2 on the vertical shaft E', having at its lower end a worm e3, meshing with a Worm-'wheel c4 on the Ystud E2, projecting from the standard A. On the worm-wheel'e4 is a pin e5,

which enters the slots g of the star-wheel G, also secured to the shaft E, so that on each revolution of the worm-wheel the pin e5 will turn the star-wheel G one-ninth of a revolution.

In order to lock the carrier-frame F to the position in which it is turned, I mount on the stud E2 a disk h, which is partly cut away. The edge of this disk fits snugly the curved recess g in the face of the star-wheel G, so that as soon as the pin e5 leaves one of the slots g the ldisk h will lock the star-wheel from revolving and hold it in the locked position until the pin e5. enters the next slot.

, At this time the cut-away portion of the disk h will be opposite the star-wheel, allowing the star-wheel to move a given distance until the disk engages the next curved recess of the wheel. The star-wheel and the carryingframe are so proportioned Vthat the sad-irons are brought iutoj position one at a time to be acted upon by thepolishing-wheel and held in position for the desired length of time. In the present instance the carrying-frame hasnine chucks for the sad-irons, and there are consequently nine slots in the star-wheel. Thechucks for the sad-irons are constructed as follows: Mounted in a socket f, Fig. 3, in a carrying-frame F is a cup-shaped chuck I, having a spindle t', which passes through a bearing f in the frame F and is provided with a nut 'Il' at its inner end. On the spindle t' is a worm-wheel i2, with which meshes a worm'j ou the shaft J, mounted in bearings f2 on the frame F. On the end of the shaft J is a peculiarly-shaped gear-wheel j', hav- .ing teeth beveled `at one end, which meshes with a gear-wheel EB on the vertical shaft E.

This wheel E3 also has teeth beveled at one end, so that when the frame F is turned the teeth of the wheel j' will readily mesh with vthe teeth of the wheel E3. By this arrangement the chuck I does not revolve except when the wheel j is in gear; with the wheel E3 and this is at a pointopposite the polishing-wheel. The chuck I'has a ring I', which is held to the chuck I by bolts Sand is also alined by pins i4, so that the ring will be held rigidly to the chuck. The ring preferably fits the object which it is intended to polish. In the present instance this Objectis the body portion of a detachable-handle sad-iron. The body portion so is held in place by a grip c on a cross-bar K, secured to the chuck I, the grip being similar' to that of an ordinary detachable handle of a sad-iron. This grip engages the cross-bar of the body portion of the IOO sad-iron and holds it rigidly in the ring of the chuck, and by simply releasing the grip 7c the ring can be detached and another placed in its stead. If it is desired to polish other sizes of irons or articles of other shapes, then the rings I are removed and rings of other shape substituted therefor.

It will be. understood that While the invention is especially applicable for polishing sadirons it may be used for polishing other shapes by simply modifying the shape of the chuck.

The operation is as follows: After the several sad-irons are placed in the chucks the machine is set in motion and the polishingwheel D adjusted so as to be in proper position to polish the surface of each iron as it comes into position. The shaft E is driven through the belt e, and the shaft E, on which the carrying-frame is mounted, is turned at intervals and locked through the star-Wheel drivin g-gear described above. As each chuck comes into polishing position the Wheel j, carried by the frame F, meshes with the wheel E3 on the shaft E', so that this one chuck is rotated through the medium of the said wheels and the Worm and Worm-Wheel 2. The chuckis rotated in this position until the frame F is moved again by the star-wheel gear, when one chuck is moved out of gear with the Wheel E3 and out of contactwith the polishing-Wheel and another one takes its place. The operator can remove the irons after they are polished during the intervals that the frame F stops and can adjust other irons in the chucks from Which the polished irons have been removed.
